WILLIAM A. CORNBROOKS, OF MOLINE, ASSIGNOR 'lO PETTIBONE,

& COMPANY, OF CHICAGO, ILLINOIS.

MULLI KEN DIE FOR UPSETTING THE ABUTTING ENDS OF RAlL-BRACES.

SPECIFICATION forming part of Letters Patent No. 367,502, dated August 2, 1887.

Application filed May 25, 1887. Serial No. 239,321. (No lnodeLl T aZZ whom it may concern.-

Be it known that I, WILLIAM A. CORN- BROOKS, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented a certain new and useful Improvement in Upsetting the Abutting Ends of Rail-Braces and Dies for the Same; and I hereby declare the following to be afnll, clear, and exact description of the same.

My invention consists in upsetting the abutting edges of rail-braces to broaden the wearing-surfaces and fit them against the rails.

My invention also consists in the general construction of my improved upsetting-die; and it further consists in details of construc tion and combinations of parts, all as hereinafter more fully set forth.

In the drawings, Figure 1 shows my improved die in side elevation, the female die being stationary and adjustable and the male die horizontally reciprocating on a bed. Fig. 2 is a broken section, showing the male die in front elevation, taken on theline 2 of Fig. 1,

and viewed in the direction'of the arrow; Fig. 3, a section showing the female die in front elevation, taken on the line 3 of Fig. 1, and viewed in the direction of the arrow; Fig. 4, a section taken on the line 4 of Fig. 3, and

0 viewed in the direction of the arrow; Fig. 5, a section taken on the lines 5 of Figs. 2 and 3, and viewed in the direction of the arrows; Fig. 6, a similar view of the same with abrace in position in the female die to be upset; Fig.

7, asimilarvicw of the female die with a brace in posit-ion after having its abutting edges upset; Fig. S, a view in perspective of a railbrace as it emerges from the forming or shaping die and before it is subjected to the opera- 0 tion of the upsetting-die; Fig. 9, a similarview of a rail-brace after its abutting edges have been upset; and Fig. 10, a section taken on the liue 10 of Fig. 7, and viewedin the direction of the arrow.

A is the female die orportion of the die comprising a metal body, 0', provided on its upper side with a rectangular recess, q, over the edges of which extend ledges 19, forming guide-flanges, for a purpose hereinafter de scribed.

In the base of the recess q is a recess, 0, somewhat oval at the entrance, asshown in Fig. 3,

its base being horizontal from the entrance through a portion of its extent and upwardly and backwardly inclined throughout the re mainder of its extent, the base being also con cave and the sides slightly converging toward it, to cause the recess to coincide with the external surface of the hollow abutment of the rail-brace B, as shown in Fig. 8. On opposite 6o sides of the mouth of the recess 0 are depressions a, and above it inclined surfaces m, extending upward and backward to shoulders at, and below the recess 0 in the face of the body 1' is a rectangular, or substantially rectangular, recess, 0".

' C is the male die or portion of the die comprising a metal body, r, having a horizontal extension, 1), on its upper side, from the lower surface of which extends the head 0, receding 7:. toward the face-of the body 1' throughout a portion of its extent and horizontal throughout the remainder of its extent, as shown, to correspond in form with the recess 0 in the female die A, the cross-section of thehead 0 be- 5 ing such with reference to that of the recess 0 as toleave, when introduced-into thelatter,

a space equal in width throughout to the thickness of the metal forming the brace 13.

On the face of the body 1*, at opposite sides {so of the head 0, to coincide with the inclined surfaces m and shoulders a of the female die, are backwardly-inclined surfaces m and shoulders a", and below the head 0' is a rectangular projection, 0, to coincide with the recess 0 in the part A.

Both dies A and O are supported on a machine of old construction and therefore not illustrated further in the present connection than is required to indicate the operatiouof o actuating the dies to upset the abutting edges of rail-braces B of the form shown in Fig. 8 to produce the form shown in Fig. 9. The female die A is secured rigidly upon the bed D of the machine, and is adjustable thereon by 5 means of set-screws, as shown, and the die 0 is secured to a reciprocating head, 0, on the bed D in a manner to cause its parts to coincide with those of the female die, the head 0 being reciprocated through the medium of pitmen E 011 opposite sides.

To upset the abuttingedges of a rail-brace,

B, the latter, by preference immediately after removing it from the forming-die, for which I have filed an application for Letters Patent concurrently with the present application,is reheated onlyaboutthe abutting edges, whereby the cooler portion is enabled to resist the action of the die. IVhen heated, as aforesaid, the brace is inserted during the back-stroke of the head 0 in inverted position into the female die A with its hollow abutment Z in the recess 0 and its base Z inthe recess 9, to the surface of which, including the inclined planes m and shoulders 11, it conforms. The male die 0 advances toward the opposing female die A and introduces the extension 1) between the guide-flanges 1), thereby pressing the brace downward on its seat and preventing displacement by the action of the male die, which at the end of its stroke has introduced the head 0 into the hollow abutment Z of the brace in the recess 0, the inclined surfaces m,and shout ders 02 against and upon the corresponding parts of the brace, all of which operations, besides removing any irregularities or imperfections in the shape produced by the formingdie, firmly hold it while the abutting edges are being upset. The upsetting is produced by the pressure of the face of the body 1" at the sides of the head 0' against the vertical sides of the opening to the hollow abutment Z, which turns them into the depressions a, producing the ridges it, and forms the ridges 7c, Fig. 9, and by the pressure of the rectangular projection 0 against the lower portion of the face of the inverted hollow abutment Zto pro duce the ridge k and shoulders 76. i

What I claim as new, and desire to secure by Letters Patent, is-

1. Upsetting the abutting ends of railbraces to flange and broaden thewearing-surfaces and fit them against the rails, substantially as described.

2. In a die for upsetting the abutting edges of rail-braces B, the combination of a female portion, A, having a recess, 0, and a male portion, 0, having a head, 0, and an extension, 19, substantially as and for the purpose set forth.

3. In a die for upsetting the abutting edges of rail-braces B, the combination of a sta tionary female portion, A, having a recess, 0, and a reciprocating male portion, 0, having a head, 0, and an extension, 12, substantially as and for the purpose set forth.

4. In a die for upsetting the abutting edges of rail-braces B, the combination of a sta tlonary adjustable female portion, A, having a recess, 0, and a horizontally-reciprocating male portion, 0, having a head, 0', and a horizontal extension, 19, substantially as and for the purpose set forth.

5. In a die for upsetting the abutting edges of raiLbraces B, the combination of a female portion, A, having a recess, {1, lateral guideflanges p, extending over the recess q, and a recess, 0, in the base of the recess r, and a male portion, 0, having a head, 0, and a horizontal extension, 19, substantially as and for the purpose set forth.

6. In a die for upsetting the abutting edges of rail-braces B, the combination of a female portion, A, having a recess, g, lateral guideflangesp, extending over the recess 9, a recess, 0, in the base of the recess q, inclined surfaces m, shoulders at, and depressions n, and a male portion, 0, having a head, 0, a horizontal extension, 1), inclined surfaces m, and shoulders n substantially as and for the purpose set forth.

7. In a die for upsetting the abutting edges of rail-braces B, the combination of a female portion, A, having a recess. q, lateral guideflangesp, extending over the recess q, a recess, 0, in the base of the recess q, inclined surfaces 112., shoulders at, depressions n, and a recess, 0 below the vertical opening to the recess 0, and a male die, 0, having a head, 0, a horizontal. extension, 1), over the head 0, inclined surfaces or, shoulders a and a projection, 0 below the head 0, substantially as and for the purpose set forth.

8. In a die for upsetting the abutting edges of railbraces B, the combination of a sta tionary adjustable female portion, A, having a recess, q, lateral guide-flanges 1), extending over the recess q, a recess, 0, in the base of the recess q, having its sides converging toward a concave base horizontal from the vertical opening to the recess throughout part of its extent and backwardly and upwardly inclined throughout the remainder of its extent, inclined surfaces m, shoulders a, vertical depressions n, and a recess, 0 below the vertical opening to the recess 0, and a male portion, 0, having ahead, 0, corresponding to the form of the recess 0 in the female portion A,
